A build up of mould is a common issue in bathrooms due to the excess moisture from showering and bathing. If you’ve noticed some mould or are battling recurring mould, experts have revealed a budget kitchen staple that can assist in its removal.

Bathroom and kitchen specialists, PlumbNation, suggested using salt as an effective method to remove mould and prevent it from returning, stating “it’s affordable, natural, and easy to use”. Salt can be purchased from Asdafor 65p, reports the Liverpool Echo.

The experts said: “Salt is a non-toxic, natural substance that’s safe for you, your family, and pets. It doesn’t emit harmful fumes or leave behind toxic residues, making it an eco-friendly choice for household cleaning. Using salt helps maintain a healthy environment without compromising indoor air quality.”

They added: “It’s inexpensive and commonly found in most households, so there’s no need to purchase special cleaners. This accessibility allows you to address mould issues promptly without incurring extra costs. Having salt on hand means you can tackle mould as soon as it appears.

“Salt absorbs moisture from the environment, which helps to kill mould that thrives in damp areas. By reducing humidity on surfaces, salt creates conditions that are less favourable for mould growth. This moisture control helps prevent future mould infestations.”

Salt has the ability to extract moisture from mould spores, leading them to dehydrate and perish. This method effectively eradicates existing mould colonies on your tiles and grout. The dehydration of mould halts its life cycle and stops it from spreading elsewhere.

Moreover, salt can hinder the proliferation of bacteria and fungi, thus preventing the spread of mould. It interferes with the cellular processes of these microorganisms, rendering surfaces less welcoming to them.

Utilising salt not only eliminates mould but also aids in maintaining cleaner surfaces for extended durations.

How to utilise salt for mould removal.

Materials Needed

  • Salt (table salt or sea salt)
  • Warm water
  • Lemon juice (optional)
  • Soft brush or sponge
  • Clean cloth

Instructions

  1. Make a Salt Paste – In a bowl, mix salt with a small amount of warm water to create a thick paste. Optional: Add a few drops of lemon juice to the paste. Lemon juice has natural antibacterial properties and a fresh scent, enhancing the effectiveness of the mixture.
  2. Apply the Paste -Spread the salt (and lemon juice) paste generously over the mouldy areas on your tiles and grout.
  3. Let It Dry -Allow the paste to dry completely on the surface. Leaving it overnight is ideal. The drying process helps the salt absorb moisture from the mould.
  4. Scrub the Area – Use a soft brush or sponge to gently scrub the dried paste and remove the mould.
  5. Rinse and Dry – Rinse the tiles thoroughly with warm water to remove any residue. Wipe the area dry with a clean cloth to prevent new mould growth.

Tips to Prevent Mould from Returning

  • Improve Ventilation – Use an exhaust fan or open windows to reduce humidity in the bathroom.
  • Dry Surfaces After Use – Wipe down tiles and grout after showers to remove excess moisture.
  • Fix Leaks Promptly – Repair any leaks in taps or pipes quickly to prevent moisture build-up.
